Feed capable of regulating intestinal tracts of grouper

Abstract

The invention relates to the technical field of feed, in particular to feed capable of regulating intestinal tracts of grouper. The feed is prepared from substances in parts by weight as follows: 25-45 parts of fish meal, 10-20 parts of soybean meal, 5-8 parts of pregelatinized starch, 20-30 parts of flour, 3-10 parts of fresh oyster meat, 5-15 parts of fresh mussel meat, 3-8 parts of clam worms, 8-10 parts of squid meal, 5-8 parts of krill meal, 3-8 parts of a yeast extract, 3-5 parts of fairy shrimps, 3-8 parts of spirulina powder, 5-8 parts of soybean phospholipid, 4-6 parts of red yeast rice, 0.2-0.4 parts of calcium lactate EPA, 1-3 parts of semen plantaginis powder, 0.5-0.8 parts of a complex enzyme preparation, 0.5-0.8 parts of a compound microecological preparation, 0.2-0.8 parts of alpha-peptidoglycan and 3-8 parts of soybean protein powder. The complex enzyme preparation, a microbial preparation and an immunological preparation are added to the feed for the grouper, intestinal florae of the grouper can be effectively regulated, digestive absorption can be improved, the immunity of the grouper can be improved, and the feed has balanced nutrients and contains no antibiotics.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for regulating the intestinal tract of grouper fish. Background technique [0002] Grouper is one of the important high-grade marine cultured fish in my country. It has the advantages of fast growth, high survival rate, and high-density breeding. Its commercial fish meat is smooth and tender, delicious and nutritious. With the growing maturity of large-scale artificial breeding technology of grouper, artificial breeding of grouper has developed vigorously in Hainan, Fujian, Guangdong and other provinces. Grouper is a high-end species of marine culture. At present, farmers mostly use chilled miscellaneous fish for cultivation. Although artificial compound feed named after grouper can be seen on the market, its production formula is actually different from that of the so-called grouper. There is no difference in the formulation of seawater fish feed. This kind of feed is diff...

AI Technical Summary

Problems solved by technology

This kind of feed is difficult to meet the nutritional needs of a certain type of sea fish raised. The characteristics of this type of compound feed are high waste, low absorption and utilization rate, heavy pollution, and poor breeding effect, and it is easy to cause slow growth of farmed fish. Weak constitution and poor resistance to disease and stress seriously restrict the development of grouper aquaculture industry. Although there are researches on grouper nutrition in China, the formula nutrition and processing technology are not ideal

However, fresh miscellaneous fish are unbalanced in nutrition, low in utilization rate, easy to cause water pollution, and easy to bring pathogenic bacteria, leading to the prevalence of grouper diseases and increased mortality
